The Dallas Cowboys have placed QB Jon Kitna (back) on Injured Reserve, ending his 2011 season. In a corresponding move, the team has signed practice squad WR Dwayne Harris to their active roster. The team also signed free-agent QB Chris Greisen (Cowboys) to their practice squad.

Dallas Cowboys owner/general manager Jerry Jones said he is not sure if QB Jon Kitna (back) or FB Tony Fiammetta (illness) will be able to play again this season. The team has still not been able to determine the origin of Fiammetta's illness but he has been experiencing nausea when he has tried to practice. Kitna's back has not been responding to treatment.

Dallas Cowboys QB Jon Kitna might be called upon to serve as a holder on field goal and extra point attempts if P Mat McBriar (foot) cannot go in Week 9. QB Tony Romo served in the role in the second half of the Week 8 game when McBriar left the game early. Kitna has never held in an NFL game.

Dallas Cowboys QB Tony Romo (rib) has a rib fracture, which he suffered during Week 2 against the San Francisco 49ers. He will not return to the team's Week 2 game, and his status for Week 3 is uncertain at this point. QB Jon Kitna has replaced him in the starting lineup.

Fantasy Tip: Definitely not a good start for Romo, who missed a significant amount of time last season due to injury. Kitna would start should Romo continue to miss time, which slightly decreases the fantasy potential of the Dallas offense. If you do not have a capable backup to depend upon, Kitna is worth picking up to cover your bases while Romo's short- and long-term availability is uncertain.

Dallas Cowboys TE Martellus Bennett said he hopes QB Jon Kitna receives a chance to compete with QB Tony Romo for the starting job next year, according to ESPNDallas.com's Tim MacMahon. "I loved playing with Kitna," Bennett said. "Kitna is one of my favorite people to play with. Just being out there on the field with that guy just makes you play even harder. He made some things happen in limited time, so I think if he got a longer chance, he'd be able to do more." The team's coaches have no plans to have a quarterback competition.

Dallas Cowboys WR Roy Williams (groin) has just 15 receptions for 218 yards since QB Jon Kitna replaced injured QB Tony Romo (shoulder) during the sixth game of the season, according to Bill Nichols, of The Dallas Morning News. Williams recorded 21 receptions in the first five games of the season.

Dallas Cowboys QB Jon Kitna (oblique) will start the team's Week 17 game if he is healthy enough to play, according to head coach Jason Garrett, reports Rainer Sabin, of The Dallas Morning News. However, owner and general manager Jerry Jones added Kitna may not be available. "No way I know medically how it would work, but he's got a real challenge playing," Jones said. QB Stephen McGee could get the start if Kitna is unable to play.

Dallas Cowboys QB Jon Kitna's (oblique) status for Week 17 is uncertain because of strained oblique muscles he suffered in Week 16, reports Charean Williams, of the Fort Worth Star-Telgram. Kitna received pain-killing shot after being injured in Week 16 but it did not help him.

Dallas Cowboys QB Jon Kitna said he is not considering retirement and believes he can play for a few more years before retiring, reports Clarence E. Hill Jr., of the Fort Worth Star-Telegram. "I know I can play well in this league for a few more years," Kitna said. "God is going to decide how long I play in the league. It's already gone longer than I thought or anybody thought."

Dallas Cowboys QB Jon Kitna went 18-for-24 for 147 yards and three touchdowns in Week 11 against the Detroit Lions, according to The Associated Press. Kitna also rushed for 40 yards and one touchdown on four carries.
